We examined purging for weight control, diet pill use, and obesity across sexual orientation identity and ethnicity groups.
Anonymous survey data were analyzed from 24 591 high school students of diverse ethnicities in the federal Youth Risk Behavioral Surveillance System Survey in 2005 and 2007. Self-reported data were gathered on gender, ethnicity, sexual orientation identity, height, weight, and purging and diet pill use in the past 30 days. We used multivariable logistic regression to estimate odds of purging, diet pill use, and obesity associated with sexual orientation identity in gender-stratified models and examined for the presence of interactions between ethnicity and sexual orientation.
Lesbian, gay, and bisexual (LGB) identity was associated with substantially elevated odds of purging and diet pill use in both girls and boys (odds ratios [OR] range = 1.9-6.8). Bisexual girls and boys were also at elevated odds of obesity compared to same-gender heterosexuals (OR = 2.3 and 2.1, respectively).
Interventions to reduce eating disorders and obesity that are appropriate for LGB youths of diverse ethnicities are urgently needed.
我们考察了不同性取向和种族群体中为控制体重、使用减肥药和肥胖而催吐的情况。
利用联邦青年风险行为监测系统调查 2005 年和 2007 年来自不同种族的 24591 名高中生的匿名调查数据进行分析。自我报告的数据包括性别、种族、性取向身份、身高、体重以及过去 30 天的催吐和使用减肥药的情况。我们采用多变量逻辑回归分析，在按性别分层的模型中估计性取向与催吐、使用减肥药和肥胖之间的关联的比值比（OR），并检验种族和性取向之间是否存在交互作用。
女同性恋、男同性恋和双性恋（LGB）身份与女孩和男孩催吐和使用减肥药的几率显著升高有关（比值比[OR]范围为 1.9-6.8）。与同性异性恋者相比，双性恋女孩和男孩肥胖的几率也较高（OR 分别为 2.3 和 2.1）。
迫切需要针对不同种族的 LGB 青少年制定合适的减少饮食失调和肥胖的干预措施。
